What Material is Best for Mounting a Heavy, Non-Magnetic Apparatus?

[Void123]

I have a heavy apparatus I am working on which needs to be mounted onto a plate (or some other support structure). The plate material has to be high strength, light-weight, and display very weak magnetic properties. Any suggestions for a material?

Thank you.

"Heavy" might mean anything from 10kg to 1000 tonnes depending what sort of engineering you do.

Since you want it to be non-magnetic, if aluminum isn't strong enough, you could try titanium.
